The LEGO catalog for retailers is available and those who have had access to the visuals (mostly preliminary) it contains report many details on the sets expected for January 2015 which will be stamped "Justice League"(logo on the box).
I offer below a summary of the information available on Eurobricks.

76026 Gorilla Grodd Goes Bananas : Gorilla Grodd is a bigfig. This set contains theInvisible Jet piloted by Wonder Woman, a mech / exoskeleton for Batman, Captain Cold and Flash.

76027 Black Manta Deep Sea Strike : This box contains a Bat-Sub, a shark, another underwater craft for Black Manta, Robin and Aquaman.

76028 Darkseid Invasion : This box contains a ship which should be the Javelin of the Justice League. Superman, Cyborg and Hawkman are in this set with a pilot for the Javelin.

76040 Brainiac Attack : Brainiac, Superman, Martian Manhunter, Supergirl and a module for Brainiac identical to the one seen on the cover of the game LEGO Batman 3: Beyond Gotham.

It seems like the list of DC Comics sets planned for 2015 unveiled a few days ago was not quite complete: If we are to believe a comment posted at Brickset, the set 76040 Brainiac Attack should join the four other boxes planned for January 2015.

The person who describes this set, and who has probably had access to the retailer catalog which presents the preliminary visuals of the novelties, announces a spaceship in the shape of a flying saucer (the one from the LEGO Batman 3: Beyond Gotham video game visible above?), and four minifigs: Superman, Supergirl, Martian Manhunter and Brainiac.

I remind you that all this information is to be taken conditional while waiting for official confirmation from the manufacturer or visuals, even preliminary, of the boxes concerned.

Here is a list published by Idle Hands published last August 10 but gone unnoticed so far and relayed by Brickset of the four LEGO DC Comics sets expected in early 2015, including the set 76025 Green Lantern vs. Sinestro that we already know.

The other three sets give pride of place to the super-villains and should logically contain their usual enemies: Flash for set 76026 against Gorilla Grodd, Aquaman (and why not Green Arrow) in set 76027 against Black Manta and Superman in the set 76028 against Darkseid (possibly accompanied by Brainiac, his partner in the fight against Justice League).

These are obviously only guesses based on the history of the characters through the accounts and animated series available. But it seems that the Justice League in New 52 version will gradually expand ...

Below, Gorilla Grodd and Black Manta in their respective virtual version which will be featured in the LEGO Batman 3: Beyond Gotham video game. There is no guarantee at this time that these versions will be those of sets 76026 and 76027.

This list is obviously to be taken with a grain of salt pending confirmation by LEGO.

LEGO today presented LEGO DC Comics Super Heroes 76025 Green Lantern vs Sinestro (174 pieces - $ 19.99 - January 2015), with a little more enthusiasm from the public present than for the other set presented today ( 75084 Wookie Gunship).

If you want my opinion, this set is really an excellent compromise between content, minifigs and price. And the arrival of Green Lantern in a box is very good news for all those who had been disappointed by the exclusivity of the previous version produced in 1500 copies and distributed during the San Diego Comic Con in 2011.

It was DC Comics Day at the LEGO SDCC 2014 booth with the presentation of the 76023 UCS Tumbler set (already listed on the LEGO Shop at this address), which is much more impressive in real life than the official visuals, and the presence of Adam West aka Batman in the 1966 series.

The showcase serving as a display for the new sets has slightly smoked walls, and not being a specialist in photography, I have nothing better to offer you than the one below.

I had the chance to win one of 1750 copies of the minifigure of the Collector (Guardians of the Galaxy) put into play today.

Unlike the minifig of Bard the bowman (The Hobbit) distributed yesterday, this minifigure from Collector is truly exclusive to Comic Con.

Bard the bowman will be featured in one of The Hobbit sets that will be released next fall.
